HP-45 scientific calculator

The HP45 emulator has not been functional for some time. On a Nexus 5 the app displays a sequence of numbers every time a key is pressed but is totally non functional. Its well and truly broken, probably by recent changes to Android. It does not appear to be being maintained

Was brilliant but doesn't seem to work now. Just displays random junk

And used it all the time. Doesn't work on Project Fi Pixel, however, so uninstalling.

Displays random junk when started on 6.0.1

Piece of junk

It doesn't work !!!!!! Nor refund ! I wonder if Google know what you are selling ?!

Opens and begins displaying random rubbish on display and cannot be controlled.

Display goes nuts with random numbers

Worked well until I upgraded android software on galaxy s5. Garbage numbers displaying as soon as you enter a number.

WHAT HAPPENED? I've been using this app for a long time and loved it. Lost my phone, reinstalled it in my new phone only to find out it went insane in the interim. Flashes all kind of numbers like a crazy person. C'mon app creator fix this thing. I USED to love it!!!

App starts then display starts showing random numbers & characters. App is not functional. Galaxy S4. I did purchase this app

Displays garbage nbrs. Clear-x triggers mysterious calculations giving more garbage.

But now displays random numbers. Pitty.

It doesn't work !!!!!! Nor refund ! I wonder if Google know what you are selling ?!

I use this daily. I'm a RPN user and the HP45 is my "main machine". Excellent emulation and I've been using this one for 3+ years. Highly recommended.

Why does it enter the OFF state? Otherwise I would give it 5 stars.

Awesome!!!

Slow to respond to touches. Misses first keystrokes. Needs a lot of fine tuning before its acceptable. Droid RAZR Maxx.

Im a big fan & power user of HP calcs and this one is absolutely wonderful!!! It works as intended. Awesome implementation!!!

Reminds me of some of the best calculators ever made.

Superb emulation of the classic HP 45! Nice, easy to read display. Very fast response!

Cannot compute (-16.23)^3. Using y^x

Never seemed to install!! So I have nothing..

The calculator works great. Just like the original. @satoshi The Emulator works correctly. The inscription was the wrong way around but that has been fixed with the newest version as well.

Beware! Incorrect results calculating x^y. Calculator reverses x and y registers! x^y is calculated y^x.

To michael Of course there are better calculators out there. This is an early hp original. HP45 was my first calculator.

Excellent hp-45 emulator..Takes me back to my college days.......XMAN

The program appears to work fine, but it is a little slow in recognizing the touch, especially the first digit entered. Errors result.

I prefer the RPNCALC over this. However, I would love to see an HP-15c emulator come out.

Looks fantastic and I really want to use it but it will not even start on my HTC Legend. Launch and get a force close. If it gets fixed I'll try again

Sweet!

A most excellent calculator app! Probably the finest RPN calculator available for Android.

NIce interface but to buggy for me. Had problems with the calculator right after installing it. I do not recommend buying this program.
